Industrial 14Mw-2.45Mpa SZS powder&oil fired hot water boiler output 90% efficiency
Main design principles of gas hot water boiler:
1. Low investment in boiler equipment
-- gas boilers choose higher furnace load, so as to reduce the
furnace volume, because the heating surface pollution, ligation,
wear and other problems.
Higher smoke velocity and smaller size of convection heating
surface are available.
The structure of gas-fired boilers with the same capacity as
coal-fired boilers is compact, the size is small, the weight is
light and the equipment investment is obviously reduced by
reasonable arrangement of convection tube bundles.
-- gas boilers use pipelines to transport gas as fuel and do not
require fuel storage equipment.
Also do not need to blow ash, dust remover, slag removal equipment,
and fuel dryer and other ancillary equipment, is the system greatly
simplified.
2. Low operation cost
-- gas boiler has strong adaptability to heat load and flexible
adjustment in the system.
-- less auxiliary equipment, faster start-up and no fuel
preparation system can reduce various consumption brought by
preparatory work, and the power consumption is lower than that of
coal-fired boilers.
-- no need for steam heating fuel and drying fuel, steam
consumption is low.
-- less impurities in the gas, the boiler will not occur high, low
temperature heating surface corrosion, the continuous operation
cycle of the boiler is long.
3. Low maintenance cost of equipment
-- gas boiler system equipment is simple, so there are few
maintenance projects and low maintenance costs.
-- since there is no slagging and corrosion of the heating surface
at high and low temperature, it is not necessary to replace the
pipe fitting of the heating surface.

Description: | ||||||
1. The boiler is mainly designed with natural gas and light diesel oil. It is also suitable for city gas, liquefied petroleum gas, biogas, coke oven gas and mine gas. | ||||||
2. The fuel consumption is calculated based on the calorific value of natural gas 36006KJ/Nm3 and the calorific value of light oil 42705KJ/kg. | ||||||
3. We follow the principle of continuous improvement and improvement of product performance. The data of the new generation products may be changed. The data in the table is for reference only. |
